Speciiication forming part of Letters Patent No. 44,833, dated October '25, 1864.

To @ZZ whom t may concern.-

Beit known that we, JOHN T. DAVY and DAvlD B. COX, both of the city ot' Troy, in the county ot' Rensselaer and lState of New York, have invented new and useful Improveinents in Cooking and Parlor Stoves; and we do hereby declare that the tbllowing is a full and exact description thereof, reference being had to the accompanying drawings and speccation Figure l being a perspective view, with a part ot' the top cut out to show the upper end of the back tiues, Fig. 2 being a sectional view at line a of lire-box. Fig. 3 is an end sectional view of the middle ot' stove. Fig. et is a sectional view at line b, showing the oven-bottom and pipetlues, with part ot' bottom oven-plate cut out to show the bottom tlues.

Between the bottom ofthe stove and the oven-bottom l? .P are two perpendicular iiueplates, 'y i, extending from the back of the stove about two-thirds the way across the bottom, for the purpose of distributing the heat descending the flue-pipes G G in the space beneath the oven-bottom, passing it round from each and meeting at the center ot' Vtlue K, trom whence it returns and asccnds through the iiucpipe H. The tine-pipes G G and H terminate at the bottom iireplate U, which forms the top plate ot' the oven J, at which point they open into other formed tluespaces, which continue the drafts to the top ot' tire-box A. Said nue-pipes G G and Hpass through the ovenspace from top to bottom, and are set in t'roin the back plate ot' the stove, so as to leave their entire surface free for the atmospherein the oven to circulate around them, thus making a larger heating-surface for the oven than can be otherwise obtained, f upon which. the oven is made to depend mainly for its heat.

Directly over the oven is situated the ashspace T and iirebox A. In the botoni of tire-box is the grate D. It is both a shaking and dumping grate. On the left end ot' it is the shaft R, projecting through the end ot' the stove, into which the lower end ot' the perpendicular lever E is fitted. At the point E on the lever is constructed a hook or knuckle, which is made to connect with another hook, F, which is firmly attached to, being cast on the stove, and forms a fulcrum for thelever E, by which the gra-te D is moved back and forth, thus sitting the ashes from the tire into the ash-pit.

The hook or fulcrum F is so constructed that when dumping the grate D is desired the lever will leave its fulcrum as it is turned down toward the front of the stove., carrying the grate with it. dien the work ot' dumping is completed, the lever is turned back to its original place, and the grate is ri ghted.

The rolling damper N, when turned back, opens a direct passage from the dre-box to the exit-pipe O or Q, and when turned up divides the product otl combustion between the openings B B, passing thence down the tiues and tiue-pipes G G, is returned in the center tlue H, and thence passed ott1 to the chimney.

We do not claim, broadly, the use ot' independent tiue-pipes in ovens; but

What we claim, and desire to secure by Letters Patent, is

l. The tlue-pipes G G and H, (more or less,) passing' through from the top ot' the oven to the bottom of the same, in combination with the oven-space J, having tire-chamber and ash-space directly over the oven, as described and set forth.

V2. The hook or `l'ulcrum F, attached to or cast on the stove, in combination with the shaking-grate D, operating in the manner and for the purposes set forth.
